For the off-channeling case, there is a better agreement between our $S_\text{e}$ results with the \textsc{Srim} data in most of the range.   In experiments, where trajectories are not necessarily finely controlled, the projectile does indeed explore core regions of the host atoms, and that is presumably why off-channeling simulation are a better representation for the most common experiments \cite{Dorado_1993}.   At higher velocities ($v > 4 ~\mathrm{a.u.}$) further disagreement stems from combined effect of the lack of explicit deeper core electrons in the simulation and also size effects, as excitations of long wavelength plasma oscillation oscillations  are artificially constrained by the simulation supercell \cite{Schleife_2015}. It is clear that a larger cell and eventually the inclusion of more core electrons would be necessary to obtain better agreement in this region.  %The existence of plasma oscillations is detected in our simulations by persistent charge motion above a certain threshold velocity of $v \simeq 1.0~\mathrm{a.u.}$. This plasma oscillations have a dramatic effects in the components forces over individual $\mathrm{Cu}$ atoms near the track of the passing hydrogen (Fig.~\ref{fig:force_on_neighbor}). This forces persist (and oscillate) even after the proton has passed.
